The Lowdown
Alright folks, it’s Rusty here. Let’s be straight with you – the next 16 days are a tough stretch for Kennebunk Beach. We’re looking at a long, dry spell with nothing rideable until the second week finally shows a flicker of life. For the first week and a half you’d be better off finding another hobby.
The whole forecast is a flat spell. There’s a gap of about 10 days from Tuesday, August 4th with nothing but poor surf conditions. The swell energy is barely a whisper, with readings as low as 4 and the highest being just 117 on Saturday, August 15th – but even that’s weak and messy. The water temperature is sitting at 65°F, which is exactly average for this time of year, so no surprises there.
The only real standout in this entire outlook is a brief window on Saturday, August 15th. The morning is clean but tiny, with a 1ft SSE swell and a period of 9 seconds. The afternoon builds to a 3ft SSE swell, again with a 9-second period. The combined energy jumps to 117 (moderate). The catch is the wind goes cross-onshore from the SSE at 9 mph, making it choppy. It’s not pretty, but it’s the biggest bump we get. For a beach break that’s sheltered and exposed to the ENE, this SSE swell isn’t ideal, but it’s the only game in town. Crowds are possible here, so don’t expect solitude.
If you’re a beginner, 3ft is fine. For experts, it’s a waist-high dribble. The short 9-second period means it’ll be a bit weak and won’t hold shape well. Honestly, with the poor quality and the onshore wind, this setup looks more interesting for kite surfing than paddle surfing.
The rest of the forecast is a flat, wind-swapped mess. The 2ft SSE swell on Wednesday, August 5th with glassy morning conditions is tempting, but the combined energy of 49 is just too weak. The 2ft SSE on Friday, August 14th afternoon has clean cross-offshore winds, but again, tiny and short period.
It’s a lean couple of weeks, but forecasts can change. For now, stay tuned and keep your board waxed for that one Saturday session.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
